Leaders of the Argentine Jewish communities tendered a farewell dinner here to Abba Gefen, for four years a counsellor at the Israeli Embassy here, who is leaving this week for Canada, where he will fill a post on the Israeli Consulate-General in Toronto.

Among the speakers, who lauded Mr. Gefen’s achievements in the fields of diplomacy and in his contacts with the Jewish communities, were Israel’s Ambassador to Argentina, Moshe Alon, and Nachman Radzichowski, secretary-general of the local Zionist organization.
